If it was a hysterectomy I imagine the statement would read up to a week, no need for William to take any time off / maybe a day at most.
The launch of Charles announcement makes this feel more serious, if it’s nothing then why move to find a cover story. The radio channels have clearly been told to make the Kings news headline as they are only briefly mentioning Kate.
Radio 4 referred to it as major surgery just now. I might be alone in thinking this but whatever it is - it’s very serious or potentially so. The reference to protecting the children confirms that for me. It may have been ‘planned’ six hours ago.
I feel for Kate. I can’t imagine the strain she is under every single day.
